A miracle, probably. Or perhaps a ticket to Dell's headquarters and a very big stick. :-)
Seriously, looking at
I see that most Dell printers, including the 725 which seems most similar to yours, are classified as "paperweight", annotated with: "service people are happy to tell you that you should have read the marks on the box before buying". So the odds of getting this printer to work with Linux are pretty bad.
From my own experience, I can only recommend you cut your losses, sell your printer to someone who will use it according to its specifications (ie. with Windows), and buy a different one from a Linux-friendly manufacturer.
